Which integrations are available for this server?

Allows AI agents to query and control the Unity Editor, including scene hierarchy, GameObjects, components, prefabs, assets, scenes, console, editor state, play mode, input simulation, animations, materials, physics, and asset creation.

How do I use Unity MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Unity MCP Server show me the scene hierarchy" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Unity MCP Server 🚀

Unity 2021.3+ License: MIT MCP

Read this in other languages: 한국어 A Model Context Protocol (MCP) server for Unity that enables AI agents to query and control the Unity Editor. This local-optimized version is enhanced with additional tools for Behavior Trees, Window Management, and advanced GameObject/Hierarchy manipulation.

What is MCP?

MCP is an open standard by Anthropic that allows AI systems to access external tools and data. This package turns Unity into an MCP server, letting AI assistants like Antigravity, Claude, and Cursor seamlessly query your scenes, modify assets, and execute editor commands.
